Keith Sweat is an R&B singer from the late 80's and early 90's. In many of his songs, he uses the phrase " I'm gonna" or I wanna ...like, | I can make you sweat| I'm want to love you down, | I'm gon' make you say ooh | girl I love you in the night I`m gonna take it real | I want her| I'm gonna give you every little bit of my love tonight | Leave me, yes I'm gonna miss you, etc...

I believe it was referenced in Spike Lee's movie: Do the Right Thing by the charachter Sweet Dick Willie. Anyway, my buddies and I started using this line to punk someone out when they would say .." I'm gonna do this" or "I'm gonna do that..." and never delivered. We would say, "fcuker, you always talking that Keith Sweat shlt..., "I'm gonna do this" or "I'm gonna do that" and you never do shlt."
